eCOA Built for Real-World Research

Clinical outcomes fail when patients miss diaries, devices break, or sites can’t support troubleshooting. Delve Health solves this by blending modern eCOA, wearable-driven insights, and human engagement into one unified ecosystem.

Data becomes more reliable. Patients stay supported. Sites stay unburdened. Sponsors get cleaner evidence with fewer deviations and faster readouts.

  • Multilingual, global-ready eCOA + ePRO
  • Real-time QC and deviation prevention
  • BYOD or fully provisioned devices with SIM
  • Wearables + ePRO harmonized to create digital endpoints
  • Concierge support in 120+ languages
eCOA platform overview

The Three Pillars of Modern eCOA

High-performing eCOA isn’t just digital forms. It’s the intersection of patient experience, protocol rigor, and continuous support — designed to work in the real world.

Patient-Centric, Multilingual, Accessible

Mobile-first assessments with adaptive UX, multimedia prompts, and multilingual support.

Researcher-Controlled & Protocol-Driven

Branching logic, edit checks, version control, and visit structures without engineering bottlenecks.

Connected to Wearables & Human Support

Wearable signals plus concierge-supported compliance create dependable, continuous evidence.

A Flexible, Powerful Form Builder

Build protocol-aligned instruments in minutes — no custom development needed. StudyPal’s authoring tools let research teams design, test, validate, and deploy assessments faster than traditional eCOA vendors.

  • PRO, ClinRO, ObsRO, PerfRO support
  • Full branching, scoring, conditional logic
  • Audio, video, and image capture inside forms
  • Sequential forms and multi-part workflows
  • Visit windows auto-adjusted to patient behavior
  • Real-time edit checks and version control

All forms stay aligned with regulatory expectations — including FDA, EMA, and ICH E6(R3) guidance.

Subjective + Objective Data in One Place

Wearables provide objective data; ePRO captures subjective experience. Delve Health merges the two — enabling richer endpoints, early signal detection, and context around patient behavior.

  • FDA-aligned digital endpoints
  • Activity, HR, HRV, SpO₂, sleep, respiratory data
  • Correlated with symptom diaries, ClinRO, and visit forms
  • Real-time biomarker trends and alerts

This is the future of evidence generation: signals + symptoms → complete insight.

Wearables integrated with ePRO

Wearable Types Supported (Optional)

Add objective measures to ePRO when it improves endpoint sensitivity. Use BYOD or fully provisioned devices. Delve monitors device health, signal quality, and compliance—then escalates with human outreach when needed.

Activity & Sleep

Wear time, steps, sleep duration/quality, circadian patterns.

Cardiovascular

Heart rate, rhythm flags, BP, ECG where applicable.

Glucose & Metabolic

CGM + glucometers, weight/scales, metabolic tracking workflows.

Respiratory

Spirometry and home monitoring to contextualize symptoms.

SpO₂ & Physiologic

Oxygen saturation, pulse, physiologic trends, signal QC.

Sleep Labs & Home Sleep

Sleep staging/indices where available; long-term monitoring.

Temperature & Vitals

Body temperature and vital signs to support safety monitoring.

Multi-Modal Sensors

Combine multiple signals to create composite digital endpoints.

Device strategy: fit-for-purpose selection, BYOD or provisioned kits with SIM, and proactive telemetry monitoring. See Wearables & Digital Endpoints →

Where Other eCOA Vendors Stop, Humans Take Over

Software alone cannot fix missed diaries, low tech literacy, battery issues, or sync failures. Delve’s Concierge-as-a-Service™ becomes the operational engine behind your study.

  • Follow-up on missed entries in real time
  • Multilingual patient coaching & troubleshooting
  • Direct support for sites during busy visit days
  • Reduced deviations, higher compliance
  • Proactive intervention when wearable or app issues occur

It’s not just eCOA — it’s eCOA with a human safety net.
